Classic ghosts
The trailers for Frozen Empire reveal that, somehow, all of the ghosts caught by the Ghostbusters are released in the film. We don’t know how many reappear but we do know that Slimer, a green blob named after his leftover residue, will return. Also returning are the Mini Pufts, small marshmallow men who appeared in Afterlife as an homage to the original Stay-Puft Marshmallow Man.
